Many people feel a little dizzy or nauseous when reading on a train or car. This happens because your eyes see that the phone (or book) moves up and down but your body doesn't feel that movement.
I think you have that backwards -- your ears are indicating acceleration but your eyes are showing that nothing's moving. This is why looking out a window helps. You see the same motion that your ears have been sensing.
Nonetheless, the same sort of solution might be available. The desire is the same: to get the screen to indicate the same motion your ears are detecting. I wonder what the relevant frequency range is. My WAG is that the 0.1 Hz to 10 Hz range would be the worst. Lower than that, it's essentially constant. Higher than that and it's vibration (and your phone hand is probably moving anyway). This would set the timescale at which we can re-center the image. If my guess is correct, it'd be tens of seconds, which might be annoying.
The good news is that you don't need to implement this as a system service to test if it works. You can just write an app that displays some text or image and applies some correction, and then stare at it during your commute to see if it helps.
